The Resistor Wire in these elements is mounted in a compressed steel tube and fixed by compressed MgO.Applications are: Water cooled resistors, High Voltage Snubber Resistors, High Load High Temperature Load Resistors and Air Cooled Resistors in aggressive environments.

The Ohmega steel tube resistors, series WHDN, are high power, water cooled brake resistors. They are mainly used on board of vessels and, because of there construction, can be used in harsh environments.
